Jacob will need 8 fabric strips, each 6 inches wide, to create the 3 3/4 feet long rainbow-themed quilt for his baby cousin's room.
To determine the number of fabric strips Jacob needs for the quilt, he first needs to convert the length of the quilt to inches, as the fabric strips are measured in inches. Since the quilt needs to be 3 3/4 feet long, we can convert this to inches by multiplying 3.75 feet by 12 (the number of inches in a foot). This equals 45 inches.
Now, as each fabric strip is 6 inches wide, Jacob can divide the total length of the quilt (45 inches) by the width of each strip (6 inches). This calculation gives him the number of fabric strips needed: 45 inches / 6 inches per strip = 7.5 strips.
Since Jacob can't use a fraction of a fabric strip, he needs to round up to the nearest whole number. Therefore, Jacob will need 8 fabric strips to create the 3 3/4 feet long rainbow-themed quilt for his baby cousin's room.
